Patented Aug. 5, 1930 UNITED STATES Examiner PATENT OFFICE FRIEDRICHWILLIAM JOLITZ, OF WEST DULUTH, MINNESOTA COMPOSITION OF MATTER FOR USEAS A BUILDING MATERIAL No Drawing.

This invention relates to a composition of matter for use as a buildingmaterial in the formation of building blocks, bricks, slabs, sidewalks,ornamental plastic work, and

5 similar structures, one of the objects being to provide a compositionof this type which is of medium Weight, is an excellent non-conductor ofheat and cold, is not subjectto excessive expansion or contraction, ismolstureproof and sound-proof, and provides structures which can bepenetrated easily and easily cut to desired sizes.

In the production of the compositlon the following ingredients are usedin the proportions stated, namely,

.Grit. %ths of a cubic foot; grusher sand tlis of a cubic foot; mediumgroun s a of a cubic footcoke bre ze of am foot' inder breeze 5 7 CUBICfeetglgortland cement in the proportions of one to six owmater roofinmaterial 2 pounds. minim all thoroughly mixed from one to three m1nutes,only enough water being used to meet the requlrements. Ordinarily fromten to twelve gallons are required where the proportlons above statedare employed, the entlre mixture totaling seven cubic feet of batch Inexplanation of the several ngredlents used it might be stated that the"Tit 1s a sharp clean washed sand. The crusl grsa n d ls made bycrushing large rocks E'o'iftam ng quallties of cement, this crusher sandbeing screened so as to be separated from dirt and trash. The coke breeobtained from coke ovens or fur s urned to eliminate all undesirablecombustible elements and divided lnto particles graded from fine tomedium, th1s separation being free of forelgn substances which wouldotherwise impair the efficiency of the ultimate product. The underbreeze is formed of the resideepb a ied UrQ nN JE malf l'li slag isremoved from the sur- Tzfie'of molten metal, this being treated withcold Water so as to be thoroughly cleaned.

formed. It is preferred to cure the structures by placing them in anairtight curing room with a temperature of not less than sixty degreesF. nor more than ninety degrees F. In this room it is allowed to set forfrom fifty to sixty hours. The resultant structure will have greatstrength and will offer maximum resistance to compression. It mi ht bestated that the cinder breeze herein re erred to has cinders rangingfrom three-eighths inch to five-eighths inch together with finerparticles.

Extensive experiments have demonstrated the fact that the basicingredients of this composition, namely the coke breeze, cinder breezeand, more especially, the slag (preferably slag of a cream color) havecertain properties of cement and, when these ingredients are mixed andpacked they will ad here and form a hard structure, such as a block,capable of use in basement work. The entire composition but, moreespecially, a composition made up of the ingredients above mentioned,constitutes an excellent insulator.

What is claimed is:

A composition of matter for use in the formatlon of plastic structuresconsisting of the following ingredients substantially in the proportionsstated, to wit, sharp clean sand, %ths a cubic foot; finely comminutedcrushed rock, ths acubic foot; finely comminuted slag, a cubic foot;crushed coke, a cubic foot; crushed cinders of not more than fiveeighthsinch, 3 cubic feet; powdered waterproofing material, 2 pounds; andcement mixed with said ingredients in the pro ortions of one part ofcement to six of the ance of the mixture, said ingredients beingadapted, when curefi airtight gnflosm-e a a temperat ro o e e s to prouce a hard waterprooi sti'iicti eb fig' m maximum resistance tocompression.
